Specification of Letters Patent.

Patented Oct. 14, 1913.

Application filed December 11, 1912. Serial No.- 736,111.

Be it known that I, HENRY SMITH, a citizen of the United States residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Awnings, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to awnings and consists in the matters hereinafter described and then pointed. out in the appended claims.

' top plan view of the parts of Fig. 4 in folded positionwhen the awning is out of use; Fig. 6 is an'enlarged detail view partly in section on the line 6-6 .of Fig. Fig. 7 is a sectional view on the line 7-7 of Fig. 5; Fig. 8 is an enlarged detail view of the parts at the inner end of one of the arms; Fig. 9 is a detail view partly in section on the line 99'of Fig. 8; and Fig. 10 is an inverted plan view of the parts of Fig. 6.

In the drawings the same reference numerals'throughout the different views represent the same or corresponding parts, the numeral 21 designating a plate upon which the working parts of the awning are carried in juxtaposition to the structure 22 towhich the awning is applied. The awning 23 consists of a suitable length of canvas or other cloth having a front skirt 24 and mounted at its inner end upon a roller 25 supported in suitable brackets 26 fastened to the plate 21, the roller carrying a suitable sprocket wheel 27 at one end operated by a chain 28 from any suitable source to wind and unwind the awning to and from its roller or drum. A pair of folding or jointed arms is employed, one at each end of the canvas and adapted to break or fold inwardly at or near their centers. In the form shown the arms consist of inner and outer sections 29 and 30 respectively suitably jointed together at 31 so that they may break inwardly toward the center of the awning but not outwardly.

The inner end of each section 29 is carried by a suitable bracket comprising a body 32 adapted to be secured to the plate 21 by the bolts 33 or other suitable fastening means;

and forwardly and downwardly projecting upper and lower wings 33 and 34 respec-,

tively; the wings being set at an obtuse angle to the body as clearly shown in Fig. 8 in order to support the arms in a downwardly inclined position so that when the canvas is u'nrolled the weight of the arms will cause them to move outwardly and downwardly by gravity carrying the outer end of the canvas with them to its extended position. The wings 33 and 34 carry an adjustable pivotpm 35 which is pivotally mounted upon the upper wing 33 and is adapted to move forwardly and rearwa'rdly in a longitudinal slot 36 in the lower arm 34. The lower end of the pivot-pin 35 is mounted in an angular plate the upper longitudinal portion 37 of which is wider than the slot 36in order to rest upon and be carried by the adjacent faces of the wing 34, and the lower downwardly projecting portion or arm 38 extends through the slot 36 below the lower face of the wing 34 where it is provided with a screw-threaded opening to engage a correspondingly threaded adjusting bolt 39 mounted to freely revolve in the downwardly projecting end 40 of the wing 34. The bolt 39 is provided with a lock nut 41 on the inner side of the end 40 or with a set nut 42 adjacent the inner face of the downwardly projecting portion 38 of the angular plate, its outer end or head being squared of the slot 36 in order to place the pin in position more or less inclined to a vertical plane as by moving it toward or. away from the vertical body 32 of the bracket, the ends of the part 37 of the plate being beveled or rounded in order to allow its easy movement upon the wing 34. The inner ends of the arms are pivotally. connected to the pins in any suitable manner, and in practice I prefer to make. the connectionso that the joint 1 31 of the arms will be offset inwardly or toward the center of the awning with respect to the line of this connection and the outer end of the arm; and also so that the arms may be freely adjusted. For these purposes I provide the construction now to be de= scribed. The pin 35 carries a pivot plate having a sleeve 43 loosely mounted to turn thereon, the outer or free end of the late being inwardly curved or offset towar the center of the awning as at 44 and provided at the free end of its offset portion with a vertical body 45 which is provided on its inner face with engaging surfaces such'as the inclined radial teeth 46 adapted to be engaged bycorrespondingly faced teeth 47 on the correspondin body 48 on the inner end of the inner section 29 of the associated arm. The parts 45 and 48 are held in position with their teeth in engagement by means of a bolt 49 passing centrally through these parts and provided at one end with a head 50 and at its other end with a nut 51. By loosening the nut 51 the parts 45 and 48 may be separated to allow the teeth to pass over each other so that the arm may be set at any suitable inclination as shown in full and dotted lines in Fig. 8, it being obvious that it may be locked in any suitable position of adjustment by tightenmg the nut 51 upon its bolt.

In practice the arms are usually arranged in pairs, one arm of each pair atone end of the associated canvas, and with their oints 31 adapted to break inwardly toward each other as shown in Fig. 2 and to lie up against the plate 21 when the awning is rolled-up out of use as shown in Fig. 1. The outer or free ends of the sections 30 of each pair of arms are provided with a revoluble and detachable connection with the awning-pole or cross-rod 53, for which purpose plates 52 are suitably secured to the pole 53 by screws 54 as shown in Figs. 6 and 10, and the end of each section 30 of the arm is provided with a forwardly projecting ear 55 having a key-hole opening or slot 56 adapted to-receive the pintle 57 of one of the plates 52, the pintle being provided with a laterally olfset shoulder or projection 58 below the lower face of the associated car 55 and adapted to be drawn up through the slot 56 when alined therewith to enable the plate 52 to be readily removed from the car 55. The arrangement and disposition of the slot and shoulder are such that these parts are in alinement to permit removal of the plate 52 when the arms are folded inwardly parallel with the line of the building or structure 22 as shown in Figs. 5 and 6, and the shoulder is adapted to look under the ear 55 by reason of the partial revolution of the ear 55 upon the plate. 52 when the arms are in their extended or projected position-shown in Figs. 3 and 10. By' this arrangement of partsthe ears 55 freely turn upon their associated plates 52 as the arms are swung inwardly or outwardly to their difl'erent positions, while the shoulders 58 lock under their ears 55 and prevent accidental displacement of the plates 52 when the arms are extended. The connection affords eas means to readily assemble and disassemb e the arms and plates.

By reference to Fig. 8 it will be observed that the pivot-pin is outwardly inclined toward its top so that the arms are inclined outwardly; by this construction when the canvas is unrolled by suitably rotating its roller 25 the arms will swing downwardly and outwardly by gravity toward their extended position, carrying with them the cross-rod 53 to which the outer end of the canvas is attached so that as the roller is revolved to unroll the awnin the weight of the-arms Will tend to 'exten it to its position of use. By reference to Figs. 2 and 3 it will be observed that the joint 31 is offset toward the center of the awning between the outer end of the arm and the pivot-pin 35 so that as the canvas is rolled up on its roller the joint of the sections of the arm will break inwardly to permit the arms to be drawn to the folded position shown in Figs. 1 and 5 when the canvas is rolled up. The adjustment provided between the arms and plates 44 afl'ords a supplemental ad justment of the arms to any desired inclination when desired in addltion to that obtained by the angle of the pivoted connection to the brackets, and also allows the arms to e dropped down to position to hang vertically from the lates when the awning is being set-up or ta en down which is a great convenience to the workmen as it obviates the necessity of temporaril holding up the outer ends of the arms w ile the work is being done.
